Servo motor torque control problem answer
The servo motor performs torque control. One is that when the torque is getting larger and larger, the servo motor speed is slower and slower, and the other is that the larger the torque, the faster the servo speed is, and the speed is maintained when the set torque is reached. There are two types of load torque control. One is that the faster the speed, the greater the torque. If the torque control is used, the speed will be automatically reduced to reduce the output torque to the set torque. The other is the faster the torque. The smaller, the torque control will automatically speed up to reduce the torque to the set torque? Servo motor torque control problem: 1. Torque control is the control of the motor current. The magnitude of the motor current determines the load torque, which is controlled by the motor itself when the motor is dragging the load; 2. When the speed is faster, the load is smaller, and the load torque decreases as the speed increases. The servo motor current will automatically decrease. 3. The speed control is the control of the motor power frequency and voltage, which can be controlled by the inverter. 4. The faster the speed, the greater the torque, such as the water pump and the fan load, and the current increases automatically as the speed increases. 5. Pay special attention here. The load torque is small, the current of the servo motor is reduced, the motor torque is reduced, and the load is dragged. This process is the instinct of the motor. It is not controlled by others. No one can control it! 6. Special attention should be paid here. The load torque is large, the current of the servo motor is increased, the motor torque is increased, and the load is dragged. This process is the instinct of the motor. It is not controlled by others. No one can control it! 7. When the current of the motor is closed-loop controlled, the load torque is small, the current cannot be lower than the given value, the frequency and voltage of the motor will rise automatically, and the load speed will increase to increase the load torque; 8. When the current of the servo motor is closed-loop controlled, the load torque is large, and the current cannot exceed the given value. The frequency and voltage of the motor will automatically decrease and the speed will decrease, reducing the load torque. 9. If the load with increasing deceleration torque is encountered, the result of current closed-loop control must be stopped. 10. If the load with reduced speed increasing torque is encountered, the result of current closed-loop control must be synchronized to the servo motor or generated.
